The recent finding that the human version of a neurodevelopmental enhancer of the Wnt receptor Frizzled 8 (FZD8) gene alters neural progenitor cell cycle timing and brain size is a step forward to understanding human brain evolution. The human brain is distinctive in terms of its cognitive abilities as well as its susceptibility to neurological disease. Identifying which of the millions of genomic changes that occurred during human evolution led to these and other uniquely human traits is extremely challenging. Recent (...) studies have demonstrated that many of the fastest evolving regions of the human genome function as gene regulatory enhancers during embryonic development and that the human‐specific mutations in them might alter expression patterns. However, elucidating molecular and cellular effects of sequence or expression pattern changes is a major obstacle to discovering the genetic bases of the evolution of our species. There is much work to do before human‐specific genetic and genomic changes are linked to complex human traits. (shrink)

Dependency relationships within the cell cycle allow cells to arrest the cycle reversibly in response to agents or conditions that interfere with specific aspects of its normal progression. In addition, overlapping pathways exist which also arrest the cell cycle in response to DNA damage. Collectively, these control mechanisms have become known as checkpoints. Analysis of checkpoints is facilitated by the fact that dependency relationships within the cell cycle, such as the dependency of mitosis on the completion of DNA synthesis, and (...) the DNA damage checkpoint can be separated genetically. In fission yeast, Schizosaccharomyces pombe, the dependency of mitosis on prior completion of DNA synthesis is mediated through tyrosine‐15 phosphorylation of the ubiquitous mitotic regulator p34cdc2. In contrast, the arrest of mitosis caused by DNA damage acts through a separate mechanism that appears to be independent of tyrosine‐15 phosphorylation. Despite these distinct interactions with the mitotic machinery, the majority of fission yeast mutants that are deficient in mitotic arrest after DNA damage are also unable to respond to inhibition of DNA synthesis. In this essay we survey the current knowledge concerning feedback controls and checkpoints within fission yeast and relate this to information derived from other systems. (shrink)

We agree that conceptualisation is key in understanding the brain basis of emotion. We argue that by conflating facial emotion recognition with subjective emotion experience, Lindquist et al. understate the importance of biological predisposition in emotion. We use examples from the anxiety disorders to illustrate the distinction between these two phenomena, emphasising the importance of both emotional hardware and contextual learning.

Sound moves us. Nowhere is this more apparent than in our responses to genuine emotional vocalizations, be they heartfelt distress cries or raucous laughter. Here, we present perceptual ratings and a description of a freely available, large database of natural affective vocal sounds from human infants, adults and domestic animals, the Oxford Vocal (OxVoc) Sounds database. This database consists of 173 non-verbal sounds expressing a range of happy, sad, and neutral emotional states. Ratings are presented for the sounds on a (...) range of dimensions from a number of independent participant samples. Perceptions related to valence, including distress, vocalizer mood, and listener mood are presented in Study 1. Perceptions of the arousal of the sound, listener motivation to respond and valence (positive, negative) are presented in Study 2. Perceptions of the emotional content of the stimuli in both Study 1 and 2 were consistent with the predefined categories (e.g., laugh stimuli perceived as positive). While the adult vocalizations received more extreme valence ratings, rated motivation to respond to the sounds was highest for the infant sounds. The major advantages of this database are the inclusion of vocalizations from naturalistic situations, which represent genuine expressions of emotion, and the inclusion of vocalizations from animals and infants, providing comparison stimuli for use in cross-species and developmental studies. The associated website provides a detailed description of the physical properties of each sound stimulus along with cross-category descriptions. (shrink)

This Article is a contribution to the torture debate. It argues that the abusive interrogation tactics used by the United States in what was then called the “global war on terrorism” are, unequivocally, torture under U.S. law. To some readers, this might sound like déjà vu all over again. Hasn’t this issue been picked over for nearly fifteen years? It has, but we think the legal analysis we offer has been mostly overlooked. We argue that the basic character of the (...) CIA’s interrogation of so-called “high-value detainees” has been misunderstood: both lawyers and commentators have placed far too much emphasis on the dozen or so “enhanced interrogation techniques” (EITs) short-listed in government “torture memos,” and far too little emphasis on other forms of physical violence, psychological stressors, environmental manipulations, and abusive conditions of confinement that are crucial to the question of whether the detainees were tortured. Furthermore, we dispute one of the standard narratives about the origins of the program: that it was the brainchild of civilian contractor psychologists because— in the CIA’s words—“[n]on-standard interrogation methodologies were not an area of expertise of CIA officers or of the US Government generally.” This narrative ignores the CIA’s role in devising these methods, in spite of the decades of prior CIA research and doctrine about forcing interrogation subjects into a state of extreme psychological debilitation, and about how to do so—by making them physically weak, intensely fearful and anxious, and helplessly dependent. By neglecting this history and focusing on the contractors and the EITs they devised, this narrative contributes to the misunderstanding that the torture debate is about EITs and nothing else. In effect, a “torture debate” about EITs and the torture memos neglects the purloined letter in front of our eyes: the abusive conditions the CIA inflicted on prisoners even when they were not subject to EITs, including abuses that the torture memos never bothered to discuss. Unpacking what this debate is really about turns out to be crucial to understanding that such interrogation methods are torture under existing U.S. law. The U.S. Torture Act includes a clause in its definition of mental torture that was intended to ban exactly the kind of interrogation methods the CIA had researched, out of concern that our Cold War adversaries were using them: mind-altering procedures “calculated to disrupt profoundly the senses or the personality.” That is precisely the “non-standard interrogation methodology” the CIA employed after 9/11.

Anhedonia is a risk factor for suicide and poor treatment response in depressed individuals. Most evidence-based psychological therapies target symptoms of heightened negative affect instead of deficits in positive affect and typically show little benefit for anhedonia. Viewing positive scenes through virtual reality has been shown to increase positive affect and holds great promise for addressing anhedonic symptoms. In this pilot study, six participants with clinically significant depression completed 13 sessions of exposure to positive scenes in a controlled VR environment. (...) Significant decreases were found in self-reported anhedonia, depression, anxiety, and impairments in functioning from baseline to 1-month follow-up. Negative affect decreased over all 13 sessions, and positive affect increased over sessions 8–13. Results suggest that positive experiences in VR may be a novel avenue for the treatment of anhedonia in depressed individuals. (shrink)

Objective:To characterize the prevalence of hyperpalatable foods (HPF) among baby foods in the U.S. and examine the prevalence of HPF exposure and consumption from both baby food and adult food sources among infants aged 9–15 months.Methods:A U.S. baby food database as well as baby foods from three 24-h dietary recalls of 147 infants were used to identify baby foods as HPF per previous publication. HPF exposure was defined as intake of any HPF during the 3-day measurement period. To determine the (...) extent of HFP consumption, % kilocalorie (kcal) intake from HPF was characterized.Results:Only 12% of baby foods were HPF; however, nearly all participants (>90%) consumed HPF, primarily through exposure to adult foods. Younger infants (<12 months) consumed 38% [standard deviation (SD) = 23.6%] of their daily food kcal from HPF and older infants (≥12 months) consumed 52% (SD = 16.4%) of daily food kilocalorie from HPF. Most younger infants (68%) and older infants (88%) had repeated exposure to the same HPF across the measurement period.Conclusions:The prevalence of HPF among baby foods in the U.S. is low. However, almost all infants were exposed to HPF, and HPF comprised a substantial percentage of daily food kilocalorie in infants' diets. Findings highlight the transition to solid food consumption during complimentary feeding period is a critical time for early HPF exposure. (shrink)

This article investigates whether acts of plagiarism are predictable. Through a deductive, quantitative method, this study examines 517 students and their motivation and intention to plagiarize. More specifically, this study uses an ethical theoretical framework called the Theory of Reasoned Action and Planned Behavior to proffer five hypotheses about cognitive, relational, and social processing relevant to ethical decision making. Data results indicate that although most respondents reported that plagiarism was wrong, students with strong intentions to plagiarize had a more positive (...) attitude toward plagiarizing, believed that it was important that family and friends think plagiarizing is acceptable, and perceived that plagiarizing would be an easy task. However, participants in the current study with less intention to plagiarize hold negative views about plagiarism, do not believe that plagiarism is acceptable to family, friends or peers, and perceive that the act of plagiarizing would prove difficult. Based on these findings, this study considers implications important for faculty, librarians, and student support staff in preventing plagiarism through collaborations and outreach programming.

Last year marked the 20th anniversary of the Foreign Corrupt Practices Act (FCPA) of 1977. The FCPA is the first and only statute prohibiting bribery and other corrupt business practices by U.S. citizens and companies conducting business overseas. This paper provides an overview of the FCPA during the two decades of its existence. More specifically, the objectives of this paper are four-fold. First, the paper provides background information about the FCPA of 1977 and subsequent amendments in 1988. Second, the paper (...) discusses the enforcement of the FCPA since its passage by examining the number of cases prosecuted under the FCPA and the respective penalties imposed. Third, the paper discusses the economic impact of the FCPA by addressing whether the FCPA places U.S. firms at a competitive disadvantage. Fourth, the paper provides public policy recommendations to expand the reach and scope of the FCPA. It covers efforts to criminalize bribery through multilateral organizations, such as the Organization for Economic Cooperation and Development (OECD), the World Trade Organization (WTO), and the Organization of American States (OAS). It also covers bilateral arrangements and efforts by non-governmental organizations such as Transparency International. (shrink)

Psychiatric disorders usually do not have characteristic physical exam findings, imaging, or lab values. Psychiatrists therefore diagnose and treat patients largely based on reported or observed behavior, which makes collateral information from a patient’s close contacts especially pertinent to an accurate diagnosis. The American Psychiatric Association considers communication with patients’ supports a best practice when the patient provides informed consent or does not object to the communication. However, situations arise in which a patient’s objection to such communication is the product (...) of impaired decision-making and the benefits of obtaining collateral information represent best practice. In this article a framework for addressing these situations is proposed using a full decisional capacity evaluation, followed by an alternate decision-making process by concurrence from a second physician. It is recommended that a patient’s refusal to allow the gathering of collateral information should be addressed exactly like refusals for other diagnostic or treatment interventions. (shrink)

Background: Direct–to–consumer genetic testing (DTCGT) offers risk estimates for a variety of complex diseases and conditions, yet little is known about its impact on actual users, including their decisions about sharing the information gleaned from testing. Ethical considerations include the impact of unsolicited genetic information with variable validity and clinical utility on relatives, and the possible burden to the health care system if revealed to physicians. Aims: The qualitative study explored primary care patients’ views, attitudes, and decision making considerations regarding (...) DTCGT. This article focuses on the disclosure decisions participants made regarding participation, testing, and results of DTCGT, a topic which arose as a secondary aim of the study. Methods: Through four longitudinal interviews (pre–test, results, 3 and 12 months post–test) we examined twenty primary care patients’ decisions, expressed intentions, and actions regarding disclosure to immediate and extended family, friends and coworkers, and physicians about participation in and results of DTCGT. Individual interviews were analyzed using qualitative content analysis and a summative approach to describe the global themes. Results: Most participants disclosed to some immediate family; less than half disclosed to extended family; approximately half talked to friends. Most participants stated they would or might disclose to physicians about DTCGT and a few did. Conceptual themes that emerged from the data analysis include ambivalence about disclosure, consistency between intention and actual disclosure behavior and decisions, and conditional information sharing. Conclusions: Participants’ intentional and actual disclosure patterns offer insight into how they view DTCGT, weigh results, and the potential impact of DTCGT. (shrink)

First published in 1985, the _Handbook for Achieving Gender Equity Through Education_ quickly established itself as the essential reference work concerning gender equity in education. This new, expanded edition provides a 20-year retrospective of the field, one that has the great advantage of documenting U.S. national data on the gains and losses in the efforts to advance gender equality through policies such as Title IX, the landmark federal law prohibiting sex discrimination in education, equity programs and research. Key features include:_ (...) Expertise_ – Like its predecessor, over 200 expert authors and reviewers provide accurate, consensus, research-based information on the nature of gender equity challenges and what is needed to meet them at all levels of education._ Content Area Focus_ – The analysis of gender equity within specific curriculum areas has been expanded from 6 to 10 chapters including mathematics, science, and engineering._ Global/Diversity Focus_ – Global gender equity is addressed in a separate chapter as well as in numerous other chapters. The expanded section on gender equity strategies for diverse populations contains seven chapters on African Americans, Latina/os, Asian and Pacific Island Americans, American Indians, gifted students, students with disabilities, and lesbian, gay, bisexual, and transgender students. _ Action Oriented_ – All chapters contain practical recommendations for making education activities and outcomes more gender equitable. A final chapter consolidates individual chapter recommendations for educators, policymakers, and researchers to achieve gender equity in and through education._ New Material_ – Expanded from 25 to 31 chapters, this new edition includes: *more emphasis on male gender equity and on sexuality issues; *special within population gender equity challenges ; *coeducation and single sex education; *increased use of rigorous research strategies such as meta-analysis showing more sex similarities and fewer sex differences and of evaluations of implementation programs; *technology and gender equity is now treated in three chapters; *women’s and gender studies; *communication skills relating to English, bilingual, and foreign language learning; and *history and implementation of Title IX and other federal and state policies. Since there is so much misleading information about gender equity and education, this _Handbook_ will be essential for anyone who wants accurate, research-based information on controversial gender equity issues—journalists, policy makers, teachers, Title IX coordinators, equity trainers, women’s and gender study faculty, students, and parents.

It is well-established that toddlers can correctly select a novel referent from an ambiguous array in response to a novel label. There is also a growing consensus that robust word learning requires repeated label-object encounters. However, the effect of the context in which a novel object is encountered is less well-understood. We present two embodied neural network replications of recent empirical tasks, which demonstrated that the context in which a target object is encountered is fundamental to referent selection and word (...) learning. Our model offers an explicit account of the bottom-up associative and embodied mechanisms which could support children’s early word learning and emphasises the importance of viewing behaviour as the interaction of learning at multiple timescales.

Attention Restoration Theory proposes that exposure to natural environments helps to restore attention. For sustained attention—the ongoing application of focus to a task, the effect appears to be modest, and the underlying mechanisms of attention restoration remain unclear. Exposure to nature may improve attention performance through many means: modulation of alertness and one’s connection to nature were investigated here, in two separate studies. In both studies, participants performed the Sustained Attention to Response Task before and immediately after viewing a meadow, (...) ocean, or urban image for 40 s, and then completed the Perceived Restorativeness Scale. In Study 1, an eye-tracker recorded the participants’ tonic pupil diameter during the SARTs, providing a measure of alertness. In Study 2, the effects of connectedness to nature on SART performance and perceived restoration were studied. In both studies, the image viewed was not associated with participants’ sustained attention performance; both nature images were perceived as equally restorative, and more restorative than the urban image. The image viewed was not associated with changes in alertness. Connectedness to nature was not associated with sustained attention performance, but it did moderate the relation between viewing the natural images and perceived restorativeness; participants reporting a higher connection to nature also reported feeling more restored after viewing the nature, but not the urban, images. Dissociation was found between the physiological and behavioral measures and the perceived restorativeness of the images. The results suggest that restoration associated with nature exposure is not associated with modulation of alertness but is associated with connectedness with nature. (shrink)

The COVID-19 pandemic has exacerbated the drug poisoning epidemic in a number of ways: individuals use alone more often, there is decreased access to harm reduction services and there has been an increase in the toxicity of the unregulated drug supply. In response to the crisis, clinicians, policy makers and people who use drugs have been seeking ways to prevent the worst harms of unregulated opioid use. One prominent idea is safe supply. One form of safe supply enlists clinicians to (...) prescribe opioids so that people have access to drugs of known composition and strength. In this paper, we assess the ethical case for clinicians providing this service. As we describe, there is much that is unknown about safe supply. However, given the seriousness of the overdose death epidemic and the current limited evidence for safe supply’s efficacy, we argue that it is ethically permissible for clinicians to begin prescribing opioids for some select patients.

Calls for public engagement on emerging agricultural technologies, including genetic engineering of farm animals, have resulted in the development of information that people can interact and engage with online, including “Frequently Asked Questions” (FAQs) developed by organizations seeking to inform or influence the debate. We conducted a frame analysis of FAQs webpages about genetic engineering of farm animals developed by different organizations to describe how questions and answers are presented. We categorized FAQs as having a regulatory frame (emphasizing or challenging (...) the adequacy of regulations), an efficiency frame (emphasizing precision and benefits), a risks and uncertainty frame (emphasizing unknown outcomes), an animal welfare frame (emphasizing benefits for animals) or an animal dignity frame (considering the inherent value of animals). Animals were often featured as the object of regulations in FAQs, and questions about animals were linked to animal welfare regulations. The public were represented using a variety of terms (public, consumer) and pronouns (I, we). Some FAQs described differences between technology terms (gene editing, genetic modification) and categorized technologies as either well-established or novel. This framing of the technology may not respond to actual public concerns on the topic. Organizations seeking to use FAQs as a public engagement tool might consider including multiple viewpoints and actual questions people have about genetic engineering. (shrink)

Controlled human infection (CHI) studies involve the deliberate exposure of healthy research participants to infectious agents to study early disease processes and evaluate interventions under controlled conditions with high efficiency. Although CHI studies expose participants to the risk of infection, they are designed to offer investigators unique advantages for studying the pathogenesis of infectious diseases and testing potential vaccines or treatments in humans. One of the central challenges facing investigators involves the fair selection of research subjects to participate in CHI (...) studies. While there is widespread agreement that investigators have a duty to select research participants fairly, this principle also yields conflicting ethical imperatives, for example requiring investigators to both exclude potential participants with co‐morbidities since they face increased risks, but also to include them in order to ensure generalizability. In this paper we defend an account of fair subject selection that is tailored to the context of CHI studies. We identify the considerations of fairness that bear directly on selecting participants for CHI studies and provide investigators and members of IRBs and RECs with a principled way to navigate the conflicting imperatives to which these considerations give rise.

Three points that are implicit in Dixon et al.'s paradigm-challenging paper serve to make prejudice potent. First, prejudice reflects understandings of social identity usthem that are shared within particular groups. Second, these understandings are actively promoted by leaders who represent and advance in-group identity. Third, prejudice is identified in out-groups, not in-groups.

In Plato's Phaedrus, Socrates offers two speeches, the first portraying madness as mere disease, the second celebrating madness as divine inspiration. Each speech is correct, says Socrates, though neither is complete. The two kinds of madness are like the left and right sides of a living body: no account that focuses on just one half can be adequate. In a recent paper, Hugh Benson gives a left-handed speech about a psychic condition endemic among mathematicians: dianoia. Benson acknowledges that his account (...) is one-sided, but only hints at the virtues of right-handed dianoia. This note sketches a somewhat fuller picture. (shrink)

Despite the recent increase of interest in the work of Merleau-Ponty there is still a persistent tendency to overlook the uniqueness of the philosophical position he advances in Phenomenology of Perception. In this article I present a reading of Merleau-Ponty’s account of the phenomenological reduction that explains how it is original. I do this by contrasting his presentation of the reduction with that of the early Husserl, highlighting how his emphasis on the phenomenology of the ‘perceived world’ leads him to (...) reject Husserl’s conception of phenomenology as a ‘philosophical science,’ and the Kantian language in which the this account is framed. I go on to critically discuss the interpretations of the reduction advanced by Stephen Priest and Joel Smith as examples of readings that fail to fully grasp Merleau-Ponty’s account of the ‘natural attitude’ as resting on the inherent objectivizing structure that is built into perception itself. The way that these authors misinterpret Merleau-Ponty helps to make maximally clear the profound philosophical significance that he places on the phenomenology of the ‘perceived world’. (shrink)

It has recently been suggested that Merleau-Ponty’s position in Phenomenology of Perception is a unique form of transcendental idealism. The general claim is that in spite of his critique of “Kantianism,” Merleau-Ponty’s position comes out as a form of transcendental idealism that takes the perceptual processes of the lived body as the transcendental constituting condition for the possibility of experience. In this article I critically appraise this claim. I argue that if the term “idealist” is intended in a sufficiently similar (...) sense to Kant’s usage of the term in naming his position as a “transcendental idealism” then it is a misrepresentation to subsume Merleau-Ponty’s position under that term. This is because Merleau-Ponty rejects the transcendental metaphysics of the reflecting subject that underpins transcendental idealism. In its place he advocates a methodological transcendentalism that, whilst being anti-realist, is not idealist. Thus to call his position “a new kind of transcendental idealism,” as Sebastian Gardner has, is to misunderstand the significance of his existentialist break with what he sees as the “intellectualism” of this position.

Ruling Passions is Simon Blackburn’s latest attempt to defend a theory of practical reason which he calls “expressivism”.2 In the first three chapters Blackburn outlines an account of how we should understand statements of right, good and virtue, as well as their negative counterparts (“the Ethical [or Moral] Proposition”, as he terms this amalgam). This he calls “quasi-realism”. I shall describe what this position entails in the first section. Secondly I shall consider the opposition to this view advanced by McDowell (...) (1987), who in turn takes his inspiration from Wiggins (1976a, 1976b). Finally I shall assess Blackburn’s reply to McDowell and Wiggins (found in Chapter 4 of RP), and argue that it is inadequate.

Offers the first comprehensive study of Martin Heidegger's five conversational texts.

• Historical: Adam Smith, Thomas Reid; Kant; Bentham and Mill • Contemporary: Normative ethics: indirect influence through Utilitarian theory; Meta-ethics: “Humean” theories of moral motivation (Smith, Blackburn), (also influences accounts of rational action in general). Non-cognitivism (Mackie, Blackburn, Gibbard).

Say that a property is topological if and only if it is invariant under homeomorphism. Homeomorphism would be a successful criterion for the equivalence of logical systems only if every logically significant property of every logical system were topological. Alas, homeomorphisms are sometimes insensitive to distinctions that logicians value: properties such as functional completeness are not topological. So logics are not just devices for exploring closure topologies. One still wonders, though, how much of logic is topological. This essay examines some (...) logically significant properties that are topological (or are topological in some important class). In the process, we learn something about the conditions under which the meaning of a connective can be "given by the connective's role in inference.". (shrink)
